Solar inverters: pros and cons of string inverters vs. microinverters
Solar inverters have one core function: convert the direct current (DC) solar panels generate into an alternating current (AC) used in your home. There are two main types of home solar inverters: Microinverters attach to the back of each panel and are best for complex solar installations.. String inverters connect strings of panels in one central location and are best for simple installations.
How Does Heat Affect Solar Panel Efficiencies?
To further the explanation, solar panels work by having the photons from the sunlight knock electrons loose from their atoms. When the solar panel gets hotter, the number of electrons in an excited state increases. This results of having the silicon solar cell generating more current but less voltage and therefore lowers its efficiency. Thanks
